Description of problem: On my Dell XPS 13" (Core i7 3rd Gen, integrated graphics, 1080p panel), once I upgraded from 3.9.9-302 to 3.10.3-300 the display flickers continuously as soon as KMS is initialized. The regression is still present in 3.10.4-300 (already noted in Bodhi, but not downvoted since that build doesn't introduce this problem) Version-Release number of selected component (if applicable): kernel-3.10.3-300.fc19.x86_64 kernel-3.10.4-300.fc19.x86_64 How reproducible: Always Steps to Reproduce: 1. Boot the kernel in question Actual results: Garbled screen after KMS initialization (barely readable) Expected results: No regression Additional info:
Might be related to bug 986375 and 990565 -- tried the latest 3.10.x (F19) and 3.11.x (F20) kernels from Koji and the problem persists, while the last 3.9.x release works. Troubling thing is, 990565 is on a system with a Radeon card and this is on Intel
Per the Arch forum post: https://bbs.archlinux.org/viewtopic.php?id=167199 this seems to be the bug being worked on in the upstream bug tracker, now linked to this entry
Not sure this is a problem with Intel's X driver - per https://aur.archlinux.org/packages/linux-mainline-dellxps/ (mentioned in the Arch forum post) this is definitely an issue with their DRI driver. Per the suggestion in the comments on that AUR package, disabling Secure Boot and enabling the Legacy Option ROM works as a temporary workaround. At least it looks like the mainstream bug report has a solution in the works, so hopefully 3.12 will carry the fix (but will it be available for Fedora 19 users?)
